Description
Technical field
The utility model relates to a kind of non-gullet motor, especially relates to a kind of non-gullet motor with low distortion winding.
Background technology
It is high that slotless brshless DC motor has rotating speed, slotless torque, and the features such as rotor inertia is little, are widely used in electric tool, among robot and medicine equipment.The winding of non-gullet motor is different from conventional motors winding process, therefore becomes the emphasis that industry is paid close attention to.
Non-gullet motor has larger winding space relative to conventional motors, traditional winding manufacturing process can be divided into three parts, first the wire of every phase winding is wound on a hexagonal winding mould, form three-phase windings, then by compacting, winding is pressed into flat, finally the winding of flat is rolled into a drag cup winding along cylinder, winding can be connected into star-like or triangle link.
The method can not relative position effectively between pilot and wire when suppressing wire, easily makes wire be subjected to displacement, each phase winding back-emf can be caused inconsistent.Suppress again after having method to propose to use the adhesive tape of viscosity that outside winding is fixing before pressing at present, but when winding is the conductor position that can not ensure winding la m in multilayer situation.
Utility model content
The purpose of this utility model is exactly the non-gullet motor providing the low distortion winding of band that a kind of conductor arrangement is more neat, excellent performance, versatility are good in order to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of non-gullet motor with low distortion winding, comprise front end housing, rear end cap, shell, bearing, Hall element, stator, rotor, winding and rotating shaft, described front end housing is connected with shell respectively with rear end cap, described rotating shaft is arranged on front end housing and rear end cap by bearing, described Hall element is arranged on shell, and described winding and rotor are arranged in rotating shaft, and described winding and stator are oppositely arranged, it is characterized in that, described winding is flat two layer winding.
Described flat two layer winding is formed by winding mould coiling by three-phase conductor, and described three-phase conductor is wound on winding mould successively by three-phase 120 °, forms three facies tracts.
Described winding mould comprises bobbin and two end faces, and described bobbin is located between two end faces.
The conductor of described winding mould side is positioned at same layer, and opposite side conductor is positioned at other one deck.
The adjustable length of described facies tract.
The lead-out wire of every phase winding connects according to star or triangle.
Compared with prior art, the utility model has the following advantages:
1) adopt the flat winding of this structure coiling, in the process of compacting, conductor is subjected to displacement with deformation ratio traditional approach few, and conductor arrangement is more neat;
2) adopt the winding of this structure coiling, phase resistance and the back-emf of each phase winding are more symmetrical;
3) span of winding is variable, can optimize span, reduces winding resistance, optimization efficiency;
4) this Design of Dies is simple, can coiling various outer diameter, and the drag cup winding of the number of turn, has versatility.
